jaayteeto - a very honest and candid post that cuts straight to what apprears to be the problem with the fuel system on this aircraft:ok:

jayteeto 30th Nov 2018 21:43

The system had back ups and the back ups worked correctly. I still have confidence in the 135 fuel system. However, knowing your systems is essential to flight safety. All I offer here is a POSSIBLE explanation as to why a pilot MAY have had some confusion. It is NOT an excuse, because the information was still available to me in my incident.

Jay....my comment means when given two indications that generate an incongruity, or are ambiguous, or otherwise in conflict....especially when it comes to fuel quantity....go with the one that presents the worst situation.

As you very correctly tell folks re the correct action to be taken when the Red Lights illuminate....you are endorsing what I mean by the one dissenting vote rule.

Either system, quantify of low contents warning....might be wrong....heck...they both might be wrong....but go with the worst case scenario as you describe.

Elapsed Time might be ok, Fuel Quantity might be ok....but the Low Contents Warning illuminates....there is the one dissenting vote re continuing the flight.

Any one of the three that says continued flight is not right....is the dissenting vote.

Agreed totally

my #602 statement is relevant to the questions being asked. WHY did he keep going, he must have chosen to press on with no fuel.

yes he did

but he MAY have been confused by indications, he MAY NOT have been arrogant and reckless, just confused. It doesn’t change the cause, but it could explain some things

And being confused may have contributed to his inability to control his NR.

For sure he did not set out to wind up in a situation such as he did.

He was a very experienced pilot from all that I have heard.

As usual....that is what is so troubling in these events....it could have happened to most any of us.

Gevans
wha
t if he did control his Nr?

what if he misjudged the height / flared too high / pulled in power too high / was left too high with no Nr

so we agree he didn’t arrive at the ground properly, but how do you KNOW why? Assumption again? Or were you there?

That is a non sequitur

gevans35 1st Dec 2018 08:45

Confusion uses up mental capacity, maybe it affected his ability to control his Nr? Maybe he did successfully enter autorotation but misjudged his height/situation? One thing is certain, he did not control his Nr all the way to the ground. I'm not criticising, just trying to understand.

To quote jayteeto "My best pilot is one who can continue to fly when there are other important things occupying their immediate attention...."

Perfect quote methinks

aka the AUTOPILOT.

One thing to be considered in this accident is that if the pilot did not intervene at all in the fuel system we wouldn't be having this discussion.

I did reply, agreeing with you, but my post went missing.

Jevs......have you spawned a double now?

TC - not to my knowledge but I have just had to repost on the VNE thread because a post disappeared.

The only post deleted on the Vne thread is one of yours, crab@, which you deleted three days ago. No one else has a post 'disappeared', we have records of all edits; and on this thread, too.

Thanks SP - I know about the one 3 days ago which I deleted but the other one must have been finger trouble on my part then:ok:

Actually I have noticed this too. It's caused me to get lost in a thread while trying to pick up where I last read from. But as the management says; it's all lies, nothing to see here, move along ;)

Maybe it's just the internet gremlins.
